A TTORNE is Patented Dec. 13, 1938 UNITED STATES PATENT OFFICE FIBER BEARING BELT CONNECTER Ohio Application September 28, 1936, Serial No. 102,967

2 Claims.

This invention relates to belt connecters, and in particular, to belt connecters having parts pivotally interconnected by bearing members.

One object of this invention is to provide a 5 belt connecter having the opposite ends of the belt interconnected by a device including a bearing member, and a bushing of fibrous material associated therewith.

Another object is to provide a belt connecter having a pair of belt clamps pivotally engaging one another by means of a bearing member, and a bushing of fibrous material, the bearing member optionally consisting of a tubular element with a tie member passing therethrough.

Another object is to provide a belt connecter having a pair of belt clamps arranged to pivotally engage one another, each belt clamp having one arm thereof broader than the other arm.

Another object is to provide a belt connecter having a pair of belt clamps with interengaging yoke portions, a fibrous bushing and a bearing member pivotally interconnecting the interengaging yoke portions.

In the drawing:

Figure 1 is a top plan view of the belt connecter of this invention.

Figure 2 is a side elevation of the belt connecter shown in Figure 1.

Figure 3 is a central vertical section along the line 33 of Figure 2, showing the internal construction of the belt connecter.

Figure 4 is a central horizontal section along the line 44 of Figure 2, likewise showing the internal construction of the belt connecter.

Figure 5 is a bottom plan view of the belt connecter shown in Figures 1 and 2.

In general, the belt connecter of this invention consists of a pair of belt clamps pivotally interconnected by a bearing member attached to one belt clamp and a bushing of fibrous material attached to the other belt clamp.

Referring to the drawing in detail, Figure 1 shows the belt connecter of this invention as consisting of belt clamps, generally designated Ill and II, having upper and lower arms I2 and I3 interconnected through the belt ends I4 and I5 by the clamping screws 23. lhe upper belt connecter arms I2 are broader than the lower arms I3. The belt clamp II is provided with inwardly directed arms I6 having holes I! therein adapted to receive a tie member I8, such as a rivet or similar element. Surrounding the tie member I8 is a bearing member I9, in the form of a bushing of hardened steel or similar bearing material, preferably stainless steel. Surrounding the bearing member I9 is a bushing 20 of fibrous material, the outer surface of which is secured within the holes 2| in the forward directed arms 22 of the belt clamp Ill. The belt with which the belt connecter of this invention can be used may be of any suitable type, a belt of hexagonal cross section being shown.

In the assembly of the belt connecter of this invention the belt clamps I and II are placed in juxtaposition, with the arms 22 of the former extending within the arms I6 of the latter, and with the fibrous bushing 20 and bearing member I9 in place within the holes 2| in the arms 22. The tie member I8 is then inserted through the holes I! and the ends thereof upset, in a manner to prevent the removal thereof and to tie the assembly securely together.

In the operation of the belt connecter shown in Figures 1 to 5, the belt in traveling around the pulleys which it interconnects, causes the belt clamps I0 and II to flex relatively to one another around the axis of the bearing element I9 as a pivot. When this occurs the outer surface of the bearing element engages the inner surface of the fibrous bushing 20 so that the thrust between the opposite ends I4 and I of the belt is thereby sustained.

It will be understood that we desire to comprehend within our invention such modifications as come within the scope of the claims and the invention.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is:

1. In combination in a belt connecter, a pair of belt clamps, one of said clamps having inwardly directed arms provided with aligning holes to receive a tie member, the other of said clamps provided with inwardly directed arms located parallel with the first mentioned arms and having aligning holes of larger diameter than the holes in said first mentioned arms, a tie member in the holes of said first mentioned arms and interconnecting said arms, a tubular bearing element of harder material than said tie member surrounding the latter, and a bushing of relatively softer material surrounding said bearing element, said bearing element and bushing being located in the holes of said second mentioned arms whereby a durable bearing is efiected between the bearing element and bushing and a cushioning action effected between the members of said connecter.

2. A belt connecter comprising upper and lower arms and means interconnecting said arms with the belt ends, a pair of inwardly directed arms material surrounding said bearing bushing, said bushings occupying the enlarged holes of the last mentioned pair of arms and providing durable bearing means and a yielding thrust receiving element between the members of the belt con- 5 necter.
